To all whom it may concern:

Be it known that l, Orr-1o M.OTTE, acitizen of the United ldtates,residing at the city of Jamestown, in the county of Chautauqua and Stateof New York, have invented certain new and useful Improvements inConcealed Fairing-Hinges, oi: which the following, taken in connectionwith the accompanying drawings, is a specification.

T he invention relates to hinges for doors and similar constructions;and the object of the improvement is to provide a simple and durableconstruction of concealed spring hinge for doors for cupboards andsimilar constructions wherein it is desirable that of the cupboard shallbe entirely without a breaker projecting portion so that the design ofsaid exterior may not be interrupted, the concealed hinge also providing a greater freedom oi: articulation tor the door so that it swingsback out of? the way, and the spring aids in the control of the door;and the invention consists in the combinations and novel featureshereinafter set forth and claimed.

In the drawings, Figure 1 is a ifront elevation of a door with thehingesconcealed. Fig. 2 is a sectional view at line 2-42 in Fig. 1showing the construction and arrangement of thedoor and the hinge in theclosed position; and 3 is a perspective view the hinge and portions ofthe door and cabinet with the door in the closed position, parts of thedoor and adjacent portion oi: the cabinet construction beingbroken awayto reveal theposition ot the hinge when attached to the door and cabinetin the close position. Fig. 4 is a perspective view of: the portion ofthe cabinet with the hinge in the open position. Fig. 5 is a sectionalview at line 2--2 in Fig. 1, much the same as shown in Fig. 2 of thedoor and adjacent cabinet portion with the hinge in the closed position,the parts being enlarged toshow the construction and arrangement of thesame; and Fig. 6 is a similar view with the door in the partially openposition; and Fig. 7 is a similar sectional view with the door in theopen position. Fig. 8 is a perspective View of the cabinet with thehinge attached therein. in the open position, a portion of the cabinetbeing broken away and shown in dotted outline. Fig. 9 is a perspectiveview of the cabinet showing the opening for the hinge. Fig. 10 is aperspective view of the preferred term at spring tor opening theSpecification of Letters Patent.

perspective parts of the hinge septhe details hinge and door. Fig. 11 isa view. of. the di'llerent arated from one another to show of theirconstruction.

Like characters of reference rel'er to corresponding partsin the severalviews.

it he numeral 10 designates the cabinet and the numeral 11 the door,which parts are shown as made of sheet metal, though other materialsmight be used. No hinges tor the dooror other means of support appear inthe front view of theclosed door as shown in 1.

The cabinet 10 is made preferably with an inturned flange 12 which isangular in formation and extends around the door to form the seat orstop 13 for the door 11, thereby also providing the pillars 14;- eachside of said door 11 l-"in opening 15. is provided in the flange 12through which the hinge operates.

l he hinge consists oi the strap or attaching plate 16 which is providedwith spaced pivoting lugs or knuckles .16, as is common in strap or butthinges. A link plate 17 is hinged to the attaching plate 16 by means orthe pin 18, said link plate 17 being provided with spaced pivoting lugsor knuckles 17 which it into the attaching plate 16 so as to form astrong hinge joint therewith. llhelinkplate 1"! is made in the angularor curved form as shown so that when the door is open said link platepasses out through the opening and acts as a stop for said door holdingit from striking against the side of: the cabinet by striking the sideof the opening 15.

The opposite vertical edge of the link plate 17 has a pivoting lug orknuckle 22 thereon tor a hinge jointwith the attaching plate 19 whichattaches to the door 11 by means of the pin 20, the plate 19 having thespaced lugs 21 for receiving the lug 22 there between.

. In order to limit the action of the hinge part, a lug 23 is providedon plate 19 which extends over the link plate 1'? and an an gular bend 2is provided in the link plate- 17 which engages the end ofthe lug 23thereby forming a stop for the hinge parts which limits the action ofthe same so that in qthe closed 13051 51011 the parts are bracedfirnilyagainst one another and all the parts of the hinge are held incorrect relation.

in order to assist in the operation at the concealed hinge, a spring Q5is provided.

to the inner exert a strong spring The wall of the cabinet by means of awelded attaching plate 28 which holds said bend firmly in position yetpermitting the torsional turning of the reof the spring 25. The otherend e closed mally held on a torsional strain so as to pressure inaiding in the opening of the door 11. As shown in Fig. 5,,the two loops26 and 27 are twisted nearly into ahnement when the door is in position..As these loops begin to open out, as showniin Fig. 6, they exert atorsional spring action on the door, and .when the door is in the opshown in Fig. 7, nearly back to the non-torsional position.

t is apparent that the hinge can be at tached to the inner side of andwill extend out or thread through the the door 11.

as the weight of the door necessitates and that said hinges will beentirely concealed from view when in the closed posiion.

I claim as new In a door hinge, of U shapedcross-section having a doorseat elxtending outwardly from the tie side of stantially U sh inner endof said ment to th thereof pivoted to end shaped leaf being movablethroughsaid slot and engageable with said stop of the seat, saidU-shaped leaf having a shoulder formed in one side thereof, and a lugextending outdoor plate and engageable door hinge, a sheet metal frameof cross-section having a door seat of the U- a stop at the inner sideof the seat, a plate rigidly secured to the inner face of the outer sideof said U-shaped frame, a leaf of sub stantially U-shape pivoted at oneend to the inner end of said plate, a plate for attaeh ment to the backof the door having an end thereof pivoted to the opposite end of saidU-shaped leaf, said opposite end of the U- shaped leaf being movablethrough said slot and engageable with said stop of the seat, a springsecured to the inner face of the outer side of the U-frame and having aloop engaging said side of the U-frame, and a second loop interposedbetween the first named plate and the adjacent side of the -leaf.

3. In a door hinge, a sheet metal of shaped crosssection seat extendingoutwardly side of the frame, said seat being slotted to form a stop atthe inner side of plate rigidly secured to the inner face of the outerside of said U-shaped frame, a leaf of substantially U-shape pivoted atone end to the inner end of said plate, and a plate for attachment tothe back of the door having an end thereof pivoted to the Opposite endof said U-leaf, said opposite end of the -shaped leaf being movablethrough said slotand engageable with said stop of the seat.

4:. In a hinge, a pair a curved leaf pivoted parts, said leaf having ashoulder formed on the outer face of one side thereof spaced from thepivotal point, and a stop borne by the adjacent attaching part andextending across said pivotal point and engageable said shoulder to holdsaid last named attaching part at substantially an obtuse angle to theadjacent side of the curved leaf in closed position of the parts.

5. In a hinge, a pair of attaching parts, a curved sheet metal leafpivoted at its ends to said parts and formed with an angular bendbetween its ends, a lug connected at one end to the adjacent attachingpart and extending across the pivotal point be tween said last namedattaching part and said pivotal frame having a door from the inner ofattaching parts, at its ends to said OTHO M.
